Description

Technical Field

[0001] The invention relates to the technical field of hot upsetting forming, in particular to a hot upsetting forming device for processing hardware fasteners. Background Art

[0002] The working principle of the hot upsetting device is to use thermal energy and mechanical force to deform and plastically form metal materials. Specifically, the device uses a heating system to heat the metal material to a temperature at which it can plastically deform. Then, a forging system applies force to the metal material, causing it to plastically deform under the action of the die, thereby achieving the processing and forming of the metal material. When hot forging the screw, it is generally necessary to place the heated screw into the mold cavity through a gripping device, and the screw is punched by a punch with a groove to achieve the purpose of forming. When the screw is continuously processed, there is continuous friction between the surface of the screw and the mold cavity when the screw is squeezed into the mold cavity. It is easy for the coaxiality of the screw and the mold cavity to decrease and become eccentric during the hot forging of the screw, which can easily lead to deviation and dislocation of the screw rod and the head during subsequent stamping, affecting the dimensional accuracy and forming efficiency of the screw during subsequent molding.

[0014] The present invention has the following beneficial effects: 1. The present invention, through the connecting assembly and the bearing assembly, always maintains the center position of the connecting frame under the elastic action of the inner wall curvature of the two staggered sliding rings and the spring block. By keeping the screw in the center position of the connecting frame, it can reduce the friction between the connecting frame and the screw during continuous molding, resulting in an increase in the gap, which leads to a decrease in the coaxiality of the screw and the connecting frame during hot forging molding, resulting in eccentricity during subsequent molding. It can also reduce the deviation and misalignment between the screw and the screw head formed by hot forging during stamping, resulting in the screw shaft and the head being not coaxial, thereby improving the dimensional accuracy and subsequent molding efficiency during subsequent molding.

[0015] 2. The present invention places components and connects components. When the side walls of the two V-shaped elastic plates are relatively close to each other, the semicircular block is pushed to slide on the bottom surface of the screw through the movable plate, and the semicircular block slides to the heated part of the screw. Since the screw has a downward axial force under the pressure of the punch die, and the contact point is more biased toward the lower half of the inner wall of the sliding ring, the bottom of the V-shaped elastic plate and the semicircular block support the screw. This can reduce the pressure of the punch on the screw during hot forging of the screw, resulting in the high-temperature area of the screw being heated being locally sunken or deformed and twisted under the action of the pressure and downward axial force during stamping, which prevents the shape of the screw from changing during the forming process while ensuring the straightness and shape accuracy of the screw.

[0016] 3. The present invention uses a movable component. When the threaded rod rotates, it pushes the pushing frame to move upward through the eccentrically connected short rod. When the pushing frame moves upward, it pushes the bottom end of the elastic sheet through the inclined surfaces on both sides, so that the two elastic sheets slide to both sides under the push of the pushing frame and separate from the outer surface of the screw. Since the surface area of the screw heated by high temperature is relatively soft, the separation of the side walls of the two elastic sheets from the screw surface can reduce the situation in which the movable plate pushes the semicircular block to slide on the screw surface, causing scratches on the screw surface and damage to the screw surface due to friction between the two, thereby ensuring the surface quality of the screw during molding.

[0017] 4. The present invention places components and movable components, and when the pushing frame rises, it pushes the pushing frame to separate to both sides through the inclined surface, and at the same time, it drives the semicircular spring rod to slide upward along the arc inside the semicircular block under the push of the pushing frame. When the two semicircular spring rods slide upward, the two semicircular spring plates drive the elastic sheets to accumulate and cover the surface of the screw. At the same time, the sliding of the two semicircular spring rods will form a circular structure with the semicircular block between the screw and the head to be stamped. At the same time, the connection point between the two semicircular spring rods will further support it on the surface of the screw through the elastic sheet while contacting each other. The closing of the two semicircular spring plates on the surface of the screw can further prevent the shape of the screw from changing during molding, further enhance the straightness and stability of the screw during molding, and enhance the molding efficiency during molding.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The sliding plate 201 is slidably connected to the inside of the sliding frame 131. The front and back of the sliding plate 201 are fixedly connected to L-plates, which are slidably connected to the inside of the square slot 123. The connecting assembly 21 includes a sliding ring 213 rotatably connected to the end of the connecting head 212 away from the connecting rod 211, and a return spring is fixedly connected to the side of the sliding ring 213 away from the middle of the sliding disk 201; One end of the return spring away from the sliding ring 213 is fixedly connected to the inner wall of the carrying frame 121; Spring blocks 214 are provided on the front and back of the sliding ring 213.

[0030] The limiting assembly 22 includes a limiting frame 221 rotatably connected to the side wall of the top connecting rod 211. Two sliding rods are slidably connected inside the limiting frame 221, and a linear spring is fixedly connected between the two sliding rods. The outer surfaces of the two sliding rods are rotatably connected to a V-shaped elastic plate 222, and the sidewalls of the V-shaped elastic plate 222 are provided with cylindrical grooves, and the interiors of the cylindrical grooves are fixedly connected to protrusions; The front and back sides of the V-shaped elastic plate 222 are both provided with a flip plate 223 , and the flip plate 223 is rotatably connected to a horizontal plate on one side close to the carrying frame 121 ; The horizontal plate is fixedly connected to the inner wall of the connecting frame 112, and the side wall of the flip plate 223 is fixedly connected with a bending spring. The end of the bending spring away from the flip plate 223 is fixedly connected to the horizontal plate. When the two sliding rings 213 are pushed and slide up and down in an interlaced manner, the sliding of the sliding ring 213 will squeeze the side walls of the two flip plates 223 through the curvature of its inner wall. When the side walls of the two flip plates 223 are squeezed by the curvature of the inner wall of the sliding ring 213, the two flip plates 223 will rotate relative to each other.

[0031] The threaded rod 301 is slidably connected to the inside of the cylindrical groove, and the protrusion is slidably connected to the outer surface of the threaded rod 301; The placement assembly 31 includes a semicircular block 311 rotatably connected to the outer surface of the threaded rod 301 , and the interior of the semicircular block 311 is hollow; The semicircular block 311 is rotatably connected to one side of the threaded rod 301 with two movable plates 312.

The side wall of the connecting ear is rotatably connected to the side wall of the V-shaped elastic plate 222. Two inclined plates 313 are fixedly connected to the interior of the semicircular block 311. When the side walls of the two V-shaped elastic plates 222 move closer to each other, the movable plate 312 will push the semicircular block 311 to slide on the bottom surface of the screw and slide the semicircular block 311 to the heating part of the screw.

[0032] The movable assembly 32 includes a short rod 321 fixedly connected to one end of the threaded rod 301 close to the semicircular block 311, and the short rod 321 is eccentrically arranged with respect to the threaded rod 301; The outer surface of the short rod 321 located inside the semicircular block 311 is rotatably connected to a push frame 322, and the push frame 322 is slidably connected to the interior of the semicircular block 311; The side wall of the inclined plate 313 is fixedly connected with a semicircular spring rod, the semicircular spring rod is slidably connected to the inside of the semicircular block 311, and the top of the semicircular spring rod is fixedly connected with an elastic piece 323.

[0033] During use, when the screw needs to be hot-formed, the screw is first conveyed to the center of the carrier frame 121 by an external grabbing and conveying device, and then the hydraulic frame 101 is started after the external sensor detects the screw. The hydraulic frame 101 drives the sliding frame 131 to move when it is working. When the sliding frame 131 moves, one of the punches on the punch die 133 will first push the screw. After the screw is pushed into the interior of the carrier frame 121 and the connecting frame 112, the external conveying device is separated from the screw, and then the heating area of the screw is first pressed during subsequent movement. After extrusion, the hydraulic frame 101 is controlled to drive the sliding frame 131 to move backward, and the electric push rod 2 132 is started. When the electric push rod 2 132 works, it will control the punch on the punch die 133 to change its position. Then, the hydraulic frame 101 is started again. When the hydraulic frame 101 works, the replaced punch performs hot forging forming on the screw. After the forming is completed, the hydraulic frame 101 controls the sliding frame 131 to reset, and the electric push rod 1 113 is started. When the electric push rod 113 works, it will push the T-shaped disk 114 to push out the formed screw, thereby completing the forming purpose of the screw.

[0034] When the punch die 133 pushes the screw to slide into the interior of the carrier frame 121 and the connecting frame 112, the sliding of the punch die 133 will push the sliding plate 201 and the L plates on both sides to slide synchronously. When the sliding plate 201 slides, it will push the sliding ring 213 connected to it to slide through the connecting rod 211 and the connecting head 212. When the two connecting rods 211 push the sliding ring 213 to slide, the two sliding rings 213 can slide up and down in an offset manner. At this time, the two sliding rings 213 will present an 8-shaped shape, as shown in FIG. Figure 11As shown in , the screw rod to be formed at this time will be between the two sliding rings 213. At the same time, the spring blocks 214 on both sides of the connecting rod 211 will slide to the intersection of the two staggered sliding rings 213 under the action of the spring. When the screw rod slides staggeredly between the two sliding rings 213 and is between the inner walls of the two sliding rings 213, the misalignment of the two sliding rings 213 must also be able to ensure that the screw rod is in the center position of the connecting frame 112 and the carrying frame 121. Even if the screw rod is offset during subsequent forming, the curvature of the inner wall of the two staggered sliding rings 213 and the spring block 214 can still ensure that the screw rod is in the center position of the connecting frame 112 and the carrying frame 121. 4 is always kept in the center position of the connecting frame 112 under the elastic action of the connecting frame 112. By keeping the screw in the center position of the connecting frame 112, the friction between the connecting frame 112 and the screw can be reduced during continuous molding, resulting in an increase in the gap, which leads to a decrease in the coaxiality of the screw and the connecting frame 112 during hot forging, resulting in eccentricity during subsequent molding. The deviation and misalignment between the screw and the screw head formed by hot forging due to the misalignment of the screw during stamping are reduced, resulting in the screw rod and the head being not coaxial, thereby improving the dimensional accuracy and subsequent molding efficiency during subsequent molding.

[0035] When the two sliding rings 213 are pushed and slide up and down in an interlaced manner, the sliding of the sliding ring 213 will squeeze the side walls of the two flip plates 223 through the curvature of its inner wall. When the side walls of the two flip plates 223 are squeezed by the curvature of the inner wall of the sliding ring 213, the two flip plates 223 will rotate relative to each other. When the two flip plates 223 rotate relative to each other, they will push the side walls of the V-shaped elastic plate 222. At the same time, when the top limiting frame 221 pushes the sliding ring 213 to slide upward, the upward sliding of the limiting frame 221 will drive the V-shaped elastic plate 222 and the semicircular block 311 to slide synchronously and make the bottom inner wall of the V-shaped elastic plate 222 and the two elastic sheets 323 inside the semicircular block 311 contact the outer surface of the screw and provide a supporting force for it. At the same time, when the flip plate 223 pushes the side walls of the V-shaped elastic plate 222, the side walls of the two V-shaped elastic plates 222 will The two V-shaped elastic plates 222 are relatively close to each other and cover the side walls of the screw. At the same time, when the side walls of the two V-shaped elastic plates 222 are relatively close to each other, the semicircular block 311 is pushed to slide on the bottom surface of the screw through the movable plate 312, and the semicircular block 311 slides to the heated part of the screw. Since the screw has a downward axial force under the pressure of the punch die 133, and the contact point is more biased towards the lower half of the inner wall of the sliding ring 213, the support of the screw by the bottom of the V-shaped elastic plate 222 and the semicircular block 311 can reduce the pressure of the punch on the screw during hot forging of the screw, resulting in the high-temperature area of the screw being heated. Under the action of the pressure and downward axial force during stamping, the high-temperature area of the screw is locally concave or deformed and twisted after being restricted by the staggered two rings, thereby preventing the shape of the screw from changing during the forming process while ensuring the straightness and shape accuracy of the screw.

[0036] When the V-shaped elastic plate 222 drives the semicircular block 311 to rise so that the two elastic pieces 323 come into contact with the outer surface of the screw, the two elastic pieces 323 will be squeezed by the screw to rotate outward. At the same time, when the two movable plates 312 push the semicircular block 311 to slide, the sliding of the semicircular block 311 will drive the threaded rod 301 to slide synchronously. When the threaded rod 301 slides, the thread groove on the surface of the threaded rod 301 will rotate when the threaded rod 301 slides under the restriction of the protrusion. When the threaded rod 301 rotates, it will push the push frame through the eccentrically connected short rod 321 322 moves upward, and when the pushing frame 322 moves upward, it pushes the bottom end of the elastic sheet 323 through the inclined surfaces on both sides, so that the two elastic sheets 323 slide to both sides under the push of the pushing frame 322 and separate from the outer surface of the screw. Since the surface area of the screw heated by high temperature is relatively soft, the separation of the side walls of the two elastic sheets 323 from the screw surface can reduce the situation in which the movable plate 312 pushes the semicircular block 311 to slide on the screw surface, causing scratches on the screw surface and damaging the screw surface due to friction between the two, thereby ensuring the surface quality of the screw during molding.

[0037] When the pushing frame 322 rises, it pushes the pushing frame 322 to separate to both sides through the inclined surface, and at the same time, it drives the semicircular spring rod to slide upward along the arc inside the semicircular block 311 under the push of the pushing frame 322. When the two semicircular spring rods slide upward, the two semicircular spring plates drive the elastic sheet 323 to accumulate and cover the surface of the screw. At the same time, the sliding of the two semicircular spring rods and the semicircular block 311 will form a circular structure between the screw and the head to be stamped. At the same time, the connection point between the two semicircular spring rods will further support it on the surface of the screw through the elastic sheet 323 while contacting each other. By closing the two semicircular spring plates on the surface of the screw, the shape of the screw can be further prevented from changing during molding, the straightness and stability of the screw during molding are further enhanced, and the molding efficiency during molding is enhanced.
